and covering the bases of tlie antenntc ; these latter 12-jointed, 

 slender, filiform ; eyes remarkably large and prominent, their 

 lower orbits reaching right down to the base of the mandibles. 

 Thorax elongate, depressed and slightly laterally compressed, the 

 pro-mesonotal sutnre remarkably broad and shallow, crenulate 

 posteriorly ; nieso-nietanotal suture obsolete above ; posterior face 

 of the metanotum truncate, slightly concave ; legs long and slender. 

 Pedicel one-jointed, cylindrical, narrowed anteriorly, vertically 

 truncate posteriorly ; abdomen cylindrical, the constriction between 

 the basal two segments very distinct ; sting exserted, powerful. 



2 . Very similar to the ^ , slightly larger ; pro- and mesouotum 

 subequal. 



(S . " Wings with two or three closed cubital, two discoidal, and 

 a radial cell. Mandibles somewhat rudimentary. Antennae long, 

 filiform, with the 1st joint of the flagellum short, about as broad as 

 long. Clypeus broad, trapeziform. Frontal area very large, tri- 

 angular. The anteuncB are inserted behind the frontal area, at 

 the sides of the antennal carinse, which are very short, close 

 together, and placed entirely behind the froutal area. Mesonotum 

 with two strong convergent furrows. Maxillary palpi with at 

 least 5 joints. Pygidium terminated in a loiig and acute point."

There are only two species of this genus kno\\n, both found 

 within our limits. Like OdontomacJins, Drepanognathus when 

 startled and disturbed makes the most astonishing leaps, but, so 

 far as my observations go, the species of neither of the two genera, 

 unless disturbed or startled, leap as a mode of locomotion.

5 . Head, thorax and pedicel ferruginous red, closely and 

 rather coarsely punctured, granulate ; abdomen black, shining, not 

 granulate, with punctures finer and more scattered ; mandibles, 

 antenna) and legs yellow ; the whole insect covered with short, 

 sparse, erect pale hairs, and a minute, fine, sericeous shining pu- 

 bescence on the mandibles, head, antenna', thorax and legs, visible 

 only in certain lights. For the rest the characters of the genus. 



$ . Similar to the ^ ; the ocelli placed very low do\\n, almost 

 in the middle of the front of the head. 



(S . " Mandibles short, triangtdar, rather wide, but not elongate. 

 Head somewliat longer than broad, strongly constricted behind 

 the eyes and up to the occipital articulation. Concavity in front
